The 1951-54 manual transmission was essentially the same as the 1948 manual transmission, and there are some good photos in the 1951-54 service manual on this site, and in the 1951-54 Parts book. Look at both the section on the transmission and the section on the clutch.

But, essentially, you remove the 5 cap screws that attach the transmission to the clutch housing to remove the transmission (after having blocked it up, etc.). You don't remove the clutch housing itself.

Hi Steve,

I wouldn't email Buchannan, I would call them. They are very old school that way.

Yes, thanks to those gentleman.

1947 Clipper Super 8, looks to be in overall good condition. Needs brakes. $10k. Southern California.

My memory is that it should go over. Remember the sway bar doesn't move up and down, it just twists.

But I could take a picture of my Cavalier sometime today if no one else has one handy.

Even with a electronic conversion (which are, I hear, dodgy with the 6-volt electrics) you will still need the bushings in good condition, because it operates from a modified cap and rotor.

I got mine rebuilt, new bushings, etc. by these guys:

It's a standard Delco distributor (or Autolite) used on lots of Detroit iron, so the parts aren't a problem.

This is an interesting Packard-related novelty item, also a fundraiser for the Negro League History Project and the Negro League Baseball Museum.

I don't think that brake pedal, or the linkage behind it, is from a BTV or a manual brake setup.

Obviously you can rebuild it yourself. However, if for one reason or the other you prefer not to, Ross Miller of Speedwell Garage (who posts here frequently) is one trustworthy rebuilder:

Kanter Auto Products as well (also a source for rebuild kits) and they provide an exchange service, so your car does not need to be off the road. Their rebuild kit also has the option of a new stainless steel plunger.

Kanter Auto Products 1948-54 Packard Parts, Power Brakes is Group 1.322

Max Merritt has rebuild kits and also has treadle vac units available on an exchange basis

Finally, three more more vendors of note, though I have no experience with them:

Karps Power Brake in Chino, California:
KARPS Power Brake

Harmon Classic Brake, has units for exchange and kits.

Finally, these guys recently started advertising in the Packard Club newsletter:
